There was a delay after Romero missed weight the second time as the UFC attempted to negotiate a deal with Rockhold.

An agreement was eventually reached, saving the main event, though some of the shine was certainly taken off the first Australian pay-per-view since UFC 193.

Dana White, via text, on UFC 221: “Romero took this fight on short notice when Whittaker fell out and he didn’t get a full camp. I appreciate him stepping up and taking the fight. If wins he doesn’t get the belt, if Rockhold wins he’s the interim champ”
